The cheapest DIY ground-source heating is to hang an old Air Conditioner from the floor joists of a popular central room in the house and cut a hole in the floor to connect the hot side of the AC to the room. The cold side remains in the basement air. A 10,000 BTU AC unit becomes a 20,000 BTu heatpump....
Even easier; I leave my furnace's air intake open in the basement in the summer. The furnace blower pulls cooler air from the basement, runs it through the air conditioner, and it into the house. It has the additional benefit of reducing the humidity in the basement, where I'd otherwise need a dehumidifier.
Then, there is my grandpa's solution. He lived in the basement. :-) Lee -- All children are born engineers. Watch them at play. They're not just playing; they're experimenting, building and learning.
